SPRAY NOZZLE.

To (/ZZ "2 27mm it am/y comer/2 Be it known that I. lVILLLiM L.I'IA'MIL- TON. a citizen of the United States. residing at Bangor.county of Van Buren, State of Michigan, have invented certain new anduseful In'iprovements in Spray Nozzles. of which the following is aspecification.

This invention relates to improvements in spray nozzles.

The main object of this invention is to provide an improved nozzle ofthe twostream type.

A further object is to provide in a nozzle of the two-stream type animproved control valve whereby either type of spray may be Selectivelysecured, or the combined sprays.

Objects pertaining to details and economies of construction andoperation will definitely appear from the detailed description tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiluent of my invention is clearlyillustrated in the accompanying drawing forming a part of thisapplication, in which:

Fig. I is a central longitudinal section of a spray apparatus embodyingthe features of my invention, the valves being shown in full lines.

Fig. II is a detail section on a line corresponding to line 2-2 of Fig.I.

Fig. III is a transverse section on a line corresponding to line of Fig.I.

Fig. IV is a detail view mainly in longitudinal section of a modifiedform of my invention shmving the same adapted to a single nozzlesprayer.

V is a transverse section on a. line corresponding to line 5-5 of Fig.IV.

Fig. VI is a side elevation of the valves, the valve rod being brokenaway.

Fig. VII is a central longitudinal section of still another 'fOlll'l oremlnidinient of my improvements.

Fig. VIII is a cross section on a line corresponding to line 88 of Fig.VII.

Fig. IX is a sectional view through the spray head on a linecorresponding to line 9--9 of Figs. I, IV and VII.

In the drawing similar reference characters refer to similar partstl'iroughout the several views, and the sectional views are Serial No.37,201.

taken looking in the direction of the little arrows at the ends of thesect-ion lines.

In the embodiment shown in Fig. I, I illustrate my improvements asembodied. in a double nozzle structure, the nozzles being duplicates.

The nozzle body 1. has arms 2, the cap-- like nozzle tips 3 beingthreaded upon the outer ends of these arms. The nozzle arms haveoutwardly facing annular shoulders 4t forming seats for the nozzle plateThis nozzle plate has a central opening ti therein and a plurality ofopenings 7. The opening 6 is aligned with the opening 8 in thetip plate9 while the openings 7 are arranged out of alignment with this opening8.

The gasket 10 disposed between the nozzle tip 3 and the nozzle plate 5provides a nozzle chamber 11. The fluid which is discharged through theopenings 7, in escaping, sets up a swirling motion in the chanr her 11and escaping through the tip opening 8, forms a wide or broad spray. Thefluid discharged into the opening 6 passes directly into the opening 8and forms a long narrow spray, this double form of two-stream spray, asit is known in the art, being well understood.

The body 1 has a central cylindrical piston valve chamber 12 therein,the passages 13 and l t opening to this valve chamber in spacedrelation. The passage 13 communicates with the opening 7 while thepassage 14.- communicates with the opening 6 through the coupling 15.The piston valve 16 is of such length that it may be adjusted to covereither the passage 13 or 14 or to an intermediate position. This valve16 has longitudinal passages 17 therethrough so that when adjusted to anintermediate position, both passages 13 and 14 are open. The valve may,however, be adjusted to selectively close either of the passages, thusproviding for the delivery of either type of spray or a combination ofthe two types thus se ;:uring a third form of spray.

The nozzle is in the embodiment shown in Fig. I mounted upon aCOllPllllg member 18, the supply pipe being connected to the nipple 19.A valve seat 20 is provided for the supply valve 21and when this valve 2is seated, the delivery of fluid is entirely cut oif In the modificationshown in Fig. IV. I illustrate my improvements as adapted by me tosingle nozzle Sprayers, the body 22 lit-5 lli) valve body. The valve311mm stem 32 con necting it with the supply valve 33 which eoacts withthe valve seat 28 to entirely cut off the delivery of the fluid. Thevalve rod 34: is threaded into the valve 33.

The valve body 35-shown in Figs. VII and VIII is very similar to thatshown in IV and V, the main diiierence being in the form: of the valvepassages 37 and 38 the tip being the same. The passages open into thevalve cylinder 39 which is adapted to receive the same type of valve asthat shown in Fig. IV.

My improved spray nozzle is especially designed by me for spraying fruittrees, vines and other crops. It hasthe advantage of being,- easilymanipulated to deliver the ditferent character of sprays.

Having thus described my invention. what I claim as new and desire tosecure by Letters Patent, is:

1. In a sprayer,.the combination of 21- no. zle body or casing memberprovided with a variable spray head and having a piston valve chambertherein and, nozzle passages independently opening to said valve chamberin spaced relation and independently communicating with said spray head,there being a supply valve seat disposed in advance of said valvechamber, a piston control valve in: said valve chamber having a pas sagelongitudinally therethrough, said val e being adapted to be adjusted to'close or par-- tially close either of said nozzle passages or to beadjusted to an intermediate position whereby both passages are fullyopen, and a supply valve coacting with said supply valve seat forclosing said valve chamber.

2. In a sprayer, the combination of a noz-. zle body or casing memberprovided with a variable spray head and having a piston valve chamberthere n and nozzle passages independently opening to said valve chainber in spaced relation and independently communicating with said sprayhead and a piston control valve in said valve chamber having a passagelongitudinally therethrough, said valve being adapted to be ad justed toclose or partially close either of sa d nozzle passages or to beadjusted to an intermediate position whereby both passages are fullyopen.

3. In a sprayer, the combination of a body member provided with avariable spray now zle head and having a piston valve chamber thereinwith independent nozzle passages opening thereto in spaced relation,and. a piston valve adapted to be adjusted to. close either or to openboth of said passages said valve having a longitudinal passage therein.

t; A sprayer comprising a body member provided with a variable spraynozzle head and having a: piston valve chamber therein and aplurality ofnozzle passages opening thereto in spaced relation, and a piston valveadjustable in said valve chamber to Cl().-.( either oi" said passages orto simultaneously open both of the passages, said valve having alongitudinal passage therein.

In witness whereof I have hereunto set my hand.
